Answer:
Substitute in the values of both given coordinates & form 2 equations:
Find the value of B from the equation 2A - B = 1:
Substitute in the B-value to the other equation:
Find the B-value using the equation from before:
Therefore the equation Ax + By = 1 would equal:
Answer:
d
Step-by-step explanation:
cause
Percent is parts out of 100 so
45%=45/100=9/20
'of' means multiply
18 =9/20 times something
multiply both sides by 20/9 to clear fraction
360/9=something
40=something
the value is 40
32 40%
80 100
to find the answer, you do 32 times 100, the. divide that by 40 which equals 80
